HAIR-DRYING APPARATUS.

Application filed March 28, 1925, Serial No. 19,061, and in Germany May8, 1924.

My invention relates to an improved device or apparatus for drying thehuman hair by means of a heating operation and the obj ect of myinvention is to provide an apparatus for the stated purpose, whichallows of being adjusted to conform to the shape and size of the head ofa person and which will act to distribute or spread the current of hotair employed as a heating agent, and to reduce or weaken the same sothat the head of the person will be surrounded as it were, by a zone ofhot dry air, whereas in all of the hair driers hitherto suggested orpractised the hot air is ejected in the form of a more or less powerfulcurrent, acting to always strike a limited part or spot of the headonly. My improved apparatus, therefore, is particularly adapted for usein drying hair which has been curled to form permanent waves, for thereason that the waves are not injured by the milddrying operation butwill stay and keep in shape.

With the above recited and other objects in view the invention residesin the novel construction set forth in the following specification andillustrated in the accompanying drawing forming a part of thisspecification and showing for purposes of exemplification, a preferredform and manner in which my invention may be embodied and practised.

The Figure 1 of the drawing is a sectional view of the new drying aparatus. Figure 2 is a view of a further modi cation. It comprises from ageneral aspect, a globular air conduction head a with a tubular inlet 5for the attachment of a conduit connected with any suitable source ofhot air supply, and with a clamping device a for connection with anyappropriate stand or holder. Fitted to the sides of the head a in themanner of a ball to constitute, in co-operation with the latter,-

a kind of a ball and socket joint, the two shells at being held inpermanent contact with the respective counter-faces of the head by meansof a coiled spring 8 interposed therebetween,

.as will be readily understood on an inspection of the drawing.- 7

The arms thus have an extension freedom of movement with relation to thehead, the more so since the circular openings in the wall of the head,through which the arms project from the latter, have a somewhat greaterdiameter than the arm portions f.

- The outer end of the part f of the arm is connected with a hot airshell or cup h by means of a coupling similar to that hereinbeforedescribed. To this end the part f is provided with a spherical shell 9engaging in a globular shell g connected to the cup h by means of ashort-curved tube 1', the two shells gand 9 being kept in the requireddistance apart from each other by means of a coiled spring is so thatthere is extension freedom for the cup h to turn about the joint.Mounted in the cup I). is an inverted conical body 2' which has anenlarged base portion for distributing purposes as will be explainedhere inafter.

The operation of the apparatus is as follows:

Upon having adjusted the apparatus on the stand not shown by means ofthe clamp and screw c and in accordance with the stature .of the person,the inlet socket b is to be connected with the hot airconduit, notshown. The hot air then flows in the form of a current through the heada, the tubular arms f,

and the curved tubes r into the two cups h. The discharge of the hot aircurrents from the two cups 72., however, does not take place in a linearpath or in the form of a current, but the shape of the cups and theconfiguration of the conical bodies therein have the effect ofdistributing or spreading the hot air current over a large area, wherebythe energy or impact of the rushing hot airis reduced and the hair inits totality or the head of the person, is uniforml enfolded in acomparatively ca'lm zone-o drying hot air. In this manner the hair isdried without the necessity of employing protectingnets and without anyliability of deranging or impairing dressed hair and particularly haircurled to form permanent waves.

From the foregoing it will be seen that the invention affords a meansfor adjusting the apparatus to the stature and size of the head of anyperson and fordrying the hair in a more reasonable manner than hithertopractised. It goes without saying that in some cases it Will beadvisable to use more than two arms and cups or it may be sufficient touse only a single arm and a single spreading cup either by taking oflz'the one arm, when renection of the spreading cup h to the head or thearm or the arms supplying the hot air may be varied or simplified, byusing an ordinary clamping device only. For while I have shown myinvention embodied in a certain.

apparatus, it is not to be inferred that such apparatus represents theonly form in which my invention may be embodied but is illustrated anddescribed as illustration of a form now preferred by me and to makeclear the principle and method of application of my invention- Itherefore do not wish to be limited to the exact details of constructionandarrangement shown and described, as modifications are no doubtpossible, which would still come within the scope of the invention andthe claims appended hereto.

What I claim is: j

1. An apparatus for drying the human hair by means of hot air,comprising a head adapted to be attached to a hot air conduit,

spreading on s, and telescopically composed tubes pivotal y attached tothe said head and to the said cups, respectively.

2. The spreading cup having a conical spreadingbody attached 'to itsinner surface gupistantially as shown, for the purpose speci- 3. Anapparatus for drying the human hair by means of hot air, comprising'ahead adapt 1 ed to be attached to a hot air conduit, spread-' ing cups,telescopic tubes, a spherical socket joint at the one end of eachtube-for the connection with the said head, and a spherical socket jointat the other end of each tube for the connection with the two spreadingcups,

respectively, substantially as and for the purpose set forth.

4:. An apparatus for drying human hair by means of hot air comprising asupply head to be attached to a hot air conduit, mouthpieces,distributing cones within the same, telescopically composed connectingtubes, and a spherical joint at one end of each tube for connection withthe mouthp'ieces.

5. An apparatus for drying human hair by of the tubes for connectionwith the supply head and themouthpieces.

In testimony whereof I 'aflix my signature.
